g Be it known'that 1, Max Bxcmmoox, formerlya subject of the King of Belgium, now

a citizen of the German Empire, residing at- Herzogenrath, 'Rheinland, Germany, have invented certain new and useful Improvements'in Apparatus for the Manufacture ofwhichthe-following is a This invention relates to improved apparatus for the manufacture of'raw plate glass and is as to its main features a division from .thick or less. [The improved apparatus will be more my application Serial'No. 568,260 filed 22nd June, 1910, although certain details not shown in thatjapplication are. herein fully set-forth. The raw; plate glass treated by this improved apparatus-is of that high q luality which .is subsequently ground into "c ear plate glass suitable for making mirrors and'the like. The apparatus is also-Suitable for making'what 'is known at present as thin plate glass,-that is'to. slay glass about mm.

Incarrying the invention into efiect ac-- cording to the form shown, the pouring table is composed of a. plurality of sections a, a,

Over the table there is arranged a roller (1, which is adapted to traverse from end to end of the table over the sections inseries. Suitable means for: this purpose are ropes 'or like members d" on each side of the roller d. In its travel over the separate sections offth'e table .the. roller 11 is held in spaced'relation' to the'-t able. This may conveniently be effected by means of remoya'ble side ledges farrangedalong each 'ofsthe longitudinal edges ofthetable.

The evenness of the surface is thus readily maintained even in protracted use. The use of cutting up aratus which operates on the rolled sheet ater the passage of the roller is preferably in the' manufacture of the plate glass as it effectively prevents "the formation ofblemishes and it enables the separate sheets to be r e-' 1 moved independently into.lthe annealing chamber simultaneously with the rolling of the original mass it. -'This is a matter of considerable importance asthe limitation of the length of the table is no longer the rateof cooling of the-rolled glass plate, but merely the limitations associated with the' heap h.

These limitations are not so serious as those associated with the cooling of the plate and consequently by means 'of 'this'im'ention' much longer'platesmay be'rglled and also much thinner plates. The rollingpf these plates has been associated with difficulties owing to'the rapid coolingof the thin plate.
